To Reset to Voltage default:
1. Set Mode Switch to OP. PWR indicator will flash GREEN alternating
with the PROG indicator flashing RED. DB210/220 must be connected an
active command station.
2. Select Address 01 on a throttle plugged in directly to the DB210/DB220.
Make sure any Locos with address 01 are removed from the layout.
3. Set OPSW 05 to C.
See section 7.0 for instructions on setting OPSW.
The
unit will start beeping continuously.
4. Set Scale Switch to the Scale voltage you wish to reset.
5. Using the Throttle with 01 selected set speed to 0.
6. Once you have reset your desired voltage set the Mode Switch to RUN and
the voltage settings will be retained.
7. To reset additional Scale setting voltage trim repeat steps 1-8 for each
Scale setting..
Note:
Voltage trim values for all scales will reset if OpSw40 (factory default)
is Closed. All other settings will also be reset to defaults.
4.10.2 Heat Dissipation
It is normal for the DB210/DB220 to be warm to the touch when it is in use. It
is designed to absorb and dissipate the power difference between the input volt
-
age and the selected scale output stabilized voltage, at the current load being
drawn. If the unit is not able to dissipate excess heat, over temperature thermal
shutdown may occur. When the DB210/DB220 experiences a over-tempera-
ture shutdown, the booster will turn off and the DB210/DB220 will beep and
the PWR indicator will flash alternating GREEN/RED once a second. We
recommend that you locate the unit in a location where it can dissipate heat. If
you experience frequent over temperature shutdowns, you can add a small fan
to increase airflow over the rear heat sink and cool the DB210/DB220.
4.10.3 Troubleshooting DB210/DB220 Shutdowns
1. Move the DB210/DB220 so that the heat sink has a flow of cool air.
2. Place the DB210/DB220 out of direct radiant heat like sunshine or a room
heater.
3. Try direct cooling by using a small fan to blow air onto the heat sink.
4. Lower the track load current.
5. Reduce the input voltage from the power supply.
If the DB210/DB220
beeps 4 times and shuts down briefly and then comes
back on again, it is probably being run too close to its pre-set current limit. In
this case it may clip or mutilate some outgoing packets to keep the track cur-
rent within acceptable limits. To solve this problem, reduce the track current
load by setting up additional power districts to provide more total power for the
layout.
